WHAT WE DO

As a comprehensive space infrastructure company, we aim to establish a sustainable, vertically integrated business model
Interstellar is a comprehensive space infrastructure company, driving progress through our rocket business for space transportation and our satellite business for space-based hardware. In our satellite operations, we aim to enter the communications satellite market, leveraging synergies created by being a rocket manufacturer. By vertically integrating rockets and satellite communications, we are building a scalable and sustainable business model that redefines what’s possible in space exploration and utilization.

ORBITAL CLASS LAUNCH VEHICLE
ZERO
Ensuring your small satellite reaches the orbit you desire with flexible space transportation services, including dedicated launches and ridesharing, all on your schedule.

CONNECTING EVERYONE, EVERYWHERE, AND EVERYTHING
OUR STARS
With the power of vertical integration—bringing together rocket and satellite expertise—we’re revolutionizing space access to deliver fast, affordable satellite launches. Our mission is to unlock high-speed, high-capacity broadband that seamlessly connects smartphones, vehicles, and the world around us.

From the very beginning, Interstellar has emphasized the importance of crafting even the smallest rocket engine with our own hands. Our defining strength lies in our high degree of in-house design and manufacturing, which ensures unmatched flexibility in engineering. By seamlessly integrating all processes—from design and production techniques to testing and quality control—within our organization, we’ve built a development system with global competitiveness at its core.
